public BatchLSModel(OrbitDeterminationPropagatorBuilder[] propagatorBuilders,
                    List<ObservedMeasurement<?>> measurements,
                    ParameterDriversList estimatedMeasurementsParameters,
                    ModelObserver observer)

Simple constructor.

Parameters:

propagatorBuilders - builders to use for propagation

measurements - measurements

estimatedMeasurementsParameters - estimated measurements parameters

observer - observer to be notified at model calls

Method Detail

configureHarvester

protected MatricesHarvester configureHarvester(Propagator propagator)

Configure the propagator to compute derivatives.

Overrides:

configureHarvester in class AbstractBatchLSModel

Parameters:

propagator - Propagator to configure

Returns:

harvester harvester to retrive the State Transition Matrix and Jacobian Matrix

configureDerivatives

@Deprecated
protected JacobiansMapper configureDerivatives(Propagator propagator)

Deprecated.

Configure the propagator to compute derivatives.

Specified by:

configureDerivatives in class AbstractBatchLSModel

Parameters:

propagator - Propagator to configure

Returns:

mapper for this propagator

configureOrbits

protected Orbit configureOrbits(MatricesHarvester harvester,
                                Propagator propagator)

Configure the current estimated orbits.

For DSST orbit determination, short period derivatives are also calculated.

Specified by:

configureOrbits in class AbstractBatchLSModel

Parameters:

harvester - harvester for matrices

propagator - the orbit propagator

Returns:

the current estimated orbits
